Geothermal Energy
Certain places on Earth have hot springs which give off a lot of steam. The steam can be used to turn turbines to enerte electricity.
Geothermal energy is renewable.
Tidal Energy
The moving water in tides have kinetic energy. To obtain energy, a barrier called a tidal barrage is built across the mouth of a tidal river. The turbines in the barrage convert kinetic energy of the moving water to electrical energy.
What are tides?
The sea level 'rises' and 'falls' twice a day, mainly due to the gravitational attraction of the moon on the oceans and seas.
Tidal energy is renewable.
Nuclear Energy
Nuclear energy is relatively cheap but it produces toxic waste which is hard to dispose of. If there is a leakage, it could kill and harm people and other living things. Currently, nuclear energy is obtained from the splitting of the nuclei of uranium atoms (nuclear fission). This causes a lot of energy to be released, which is used ti generate electricity and to power ships and submarines.
Nuclear energy is non-renewable.
